RAF Typhoon fighter aircraft have operated alongside French aircraft in a combined operation on an underground arms cache in Syrian territory employed by the Islamic State group (IS), as stated by the UK's MoD.
The site, located using reconnaissance, was assessed as containing munitions and bombs, the statement said, and was positioned in hills just north of the ancient city of Palmyra in the heart of Syria.
"The RAF jets employed laser-guided Paveway IV weapons to target a several approach shafts leading to the facility... initial indications suggest the target was engaged successfully," officials stated.
There was no evidence of any harm to civilians in the operation conducted Saturday night and all the aircraft made a safe return, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
Daesh - also known as the so-called Islamic State - imposed jihadist rule over large swathes of Syria and Iraq until 2019.
"This action demonstrates British leadership, and commitment to operate in unison with our allies, to stamp out any re-emergence of IS and their dangerous and violent ideologies in the area," UK Defence Secretary John Healey said.
British military aircraft have conducted patrols over Syrian airspace to "prevent any attempted comeback" of Islamic State following its routing at the climactic battle in Baghuz in the year 2019, the authorities noted.
"I must thank the personnel of the UK armed forces participating in this mission for their expertise and their valour," he commented. "They were part of numerous UK service members stationed over Christmas and New Year. This mission, to remove militants who pose a risk to our way of life, highlights how UK forces are prepared to act, all year round, protecting the UK at home and influential overseas."
Last December, the US military executed what it termed a "major assault" on IS targets in the country, after an assault killed two US troops and a civilian interpreter in Palmyra.
The United Nations estimates Daesh still has between 5,000 and 7,000 fighters in Iraq and Syria.
